you could put it in the disk and rotate it with a rotor. inside of the ship ionized gaz and the rotor turns opposite direction , u could open exhost from the disc shaped ship and throw the gaz.. when the gaz finished u could close exhousts throw new ionized gaz to chamber to stop the turning rotor and prodicing violocity again an again.

This would draw more energy than it produced, the induction, and acceleration fields would be much higher load than the thermocouple, which would basically act like a solid state heat exchanger. However, this is one of your more elegant ideas, with a little polish, and some actual numbers to prototype with, it might even be testable. What's the fuel, Helium?

But in space (solar)power is cheap and free. Trading energy for propellant efficiency is a no-brainier.

Fuel could be any neutral gas or plasma. Everything from gases to the solar wind.

I know, I was just refuting the idea that this setup would somehow accelerate the reaction mass, and generate more power than you'd need (Indicative of Sig's bootstraping mindset)when AFAIK, thermodynamics are still in effect.

Indeed, in solar space, trading energy for propellant efficiency is a pretty damned good idea regardless of what you want to accelerate through space. Form the rough scale of the image, and assuming Helium as a propellant, I'd say it might be a nice translunar drive.

All right, SIGMA, you cheeky bastard, I just realized you ripped off that entire graphic from the VASIMIR project, I just saw it sans labels on Futurescape with James Woods, and Michio [censored] Kaku. If you're going to do that, at least give credit.
